Products and Algorithms

As for all Sentinel missions, the Sentinel-5P products are freely available to users via the Copernicus Open Access Hub.

Level 1B – User technical documentation

The information needed to properly use the Level 1B data can be found in Table 1:

  • MDS(Metadata Specification): contains the metadata specification of the TROPOMI Level 1b data products
  • IODS (Input Output Data Specification): description of the products that are the result from the Level 0 to Level 1b processing
  • ATBD (Algorithm Theoretical Basis Document): high level description of the algorithms used in the Level-0 to 1b data processing
  • PRF (Product Readme File): description of changes between different product versions and overall quality information (available a few months after launch)
